MCCB DC BREAKERS

A DC MCCB (Molded Case Circuit Breaker) is used to protect high-current DC circuits in solar PV systems, battery banks, inverters, and DC distribution boards. It safely disconnects the circuit during overloads or short circuits, preventing damage to equipment and reducing fire risk. Designed specifically for DC applications, it handles higher arc energy than AC breakers and is suitable for large solar and energy storage systems.
